IMPROVEMENT IN SEED-SOWERS AND CULTIVATORS.

Specification forming part of Letters Patent No. 190,839, dated May 15, 1877; application filed February 24, 1877.

To all whom it may concern:

Be it known that I, EZRA EMMERT, of Franklin Grove, in the county of Lee and State of Illinois, have invented a new and valuable Improvement in Seed-Sowers and Cultivators and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this specification, and to the letters and figures of reference marked thereon.

Figure l of the drawings is a plan view of my seed-sower and cultivator, and Fig. .3 is a longitudinal vertical sectional view of the same. Figs. 3, 4, 5, 6,7, 8, 9, l0, and 11 are detail views thereof.

This invention relates to combined seedsowers and cultivators.

The nature of said invention consists in the novel construction and arrangement of the parts, as will be hereinafter more fully set forth.

In the accompanying drawings, A desig' nates the draft-pole of my vehicle; A, the hounds thereof, and B the transporting-wheels, which turn on journals 0 0. These journals are formed upon the ends of the bottom 0 of long feed-box O, which bottom is provided with a series of seed-perforations, one of which, marked 0 is shown in Figs. 1 and 2. An inclined scatter-board, D, is fixed to said bottom, extending under said holes 0 Said bottom is provided with raised front and rear rims 0 G and also with guide-strips C 0 which are parallel therewith, as shown in Figs.2 and 10. Said guide-strips extend from end to end of said box, and between them works a perforated slide, E, which is operated by means of a lever, F, so as to open or close the seeding-perforations c at will. One end of said adj usting-leverwF extends outward behind said seed-box, and the other end is pivoted to the inside of front rim 0*, so as to have lateral vibration. Said lever sets within recess 0 of slide E and the guide-strips 0 O and the rear rim of said seed-box has enlarged openings for allowing said lateral vibration.

Above slide E are two metal plates, F and G, provided, respectively, with registeringperforations f and g. Upper plate F is fixed, but lower plate G is movable longitudinally, so as to regulate the supply of seed through the perforations 0 which are directly below said holes f and g. H designates two end pieces, one of which is shown in detail in Figs. 3 and 11. Each end piece H has two downwardly-extending perforated lugs, h h, and is detachably but firmly secured to bottom piece by means of a rod or long bolt, 0 passing transversely through said perforated lugs and said bottom piece. The middle of the bottom of each end piece is also recessed at h to allow the endwise play of extension on the end of plate F By means of these extensions the said plate is moved to regulate the feed of grain, as described. Each end piece H is also provided on its inner face at its edges with upright slightlyinclined flanges H Parallel to these are shorter flanges or ribs H the lower ends h of which are cut away, so as to allow the end of plate G to set under them. They prevent the end of said plate G from being displaced. On the top of said end piece is formed a horizontal inwardly-extending flange, H and on the sides of said end piece, near the top are two small lugs, h h

which are flat on top. In the middle (or near the middle) of each end piece is a detachable bearing-block, H, which is perforated at h for a purpose hereinafter stated, and held to said end piece by a button, h, on the outside of said block H. To remove said bearingblock, turn said button diagonally. The construction of the two end pieces H H is substantially the same.

I designates the two side pieces. Their ends set in the grooves or channels between ribs H H of the end pieces H, and their bottoms set in the grooves or channels between rims and guide-strips 0 Each side piece is provided near its upper corners with hooks I, which catchbver lugs h and help to hold box 0 together. J designates the top piece of said seed-box, which rests upon said side pieces I, and the ends of which set under flanges H H already described.

Said side pieces are perforated at j j to allow perforated lugs k k to pass outward, so as to be engaged by hooks L L pivoted to the sides of bottom piece 0 These lugs are formed on the sides of a detachable trans verse partition, K, which divides said seed box into two equal portions. Said partition is perforated at It near its bottom to serve as a bearing for the inner iournals m of feeders M. The feeders are triangular in cross-section, and have their three sides curved or hollowed, as shown. Said feeders M agitate the seed in the seed-box and force it through the seeding-holes already described.

Each feeder-shaft is provided on its outer end with a spur-pinion, )l. (Shown in detail in Fig. 5.) These piuious. respectively. engage with internallygeared rings or wheels N N, which are arranged on the inside of the transporting-wheels and hung to the spokes thereof by hooks. Said rings are easily detachable from said transporting-wheels, but will not be casually displaced. They give ro tary motion to said shafts.

All the parts hereinbefore described may be readily separated for convenience in storing and transportation as freight; but when secured together, as above described, their attachment is firm enough to answer all practical purposes.

Bottom piece C is provided with two perforated supporting plates or brackets, 0, extending obliquely downward and rearward from near the ends of said bottom piece, and the end of tongue A is provided with a perforated double plate or bracket. 0. The aforesaid plates or brackets 0 0 support shafts or rods 1, on which are pivoted the front upper ends of draft-bars Q separated by sleeves q. The rear ends of said drag-bars are cleft, and in each of them turns a small gear-wheel, R. S designates a series of cultivator-teeth, which are pivoted in the cleft rear ends of said draft-bars or drag-bars Q. Each of said teeth is provided with a bar, S, ext-eudingtorward from above its pivotal point. and having cogs x which mesh with said wheel R. Should a tooth come into contact with an unyielding: substance, pinion or wheel It will turn sufficiently to allow said tooth to be freed, though holding it firmly enough to overcome the ordinary resistance of the soil. By means of said pinion or gear-wheel R the said tooth can be set at any angle desired.

Fig. 4 shows a modification of said cultivator-tooth, in which the forward end of arm S is provided with a curve-slotted upward extension, s, that works tightly over a pin or bolt, 8 fixed to drag-bar Q. Both forms of cultivator tooth and attachment may be used in the same machine, if desired.

T designates two brace-bars, each of which is secured to the back of one of the two series of drag-bars Q, and provided with a staple, t, on the top ofits middle portion. Through said staple passes an adjusting-lever, U, which turns loosely on one of the rods P, and is provided with a handle,U. Each lever U catches, when in its highest position, upon one of two books, V V, which are fixed to bottom piece 0. By means of these devices the cultivatorteeth may be raised out of engagement with the ground whenever desired, and locked in such position, so as to be inoperative. The feeder-shafts are journaled at their outer ends in holes h of detachable bearing-blocks H.

Many changes may be made in the apparatus above described without departing from the spirit of my invention.

What I claim as new, and desire to secure by Letters Patent, is-

The combination of bottom piece (1 having front and rear rims O and guide-strips G with perforated side pieces I, partition K, having lugs jj, and pieces H, having flanges H H H and books 1 substantially as shown and described.

In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.

EZRA EMMERT.
